A couple easy steps:
- Log into site admin
- Under Appearance, Select Editor
- Use Command/F to pop up search screen (in upper right)
- Type Site-Description, which highlights the CSS codes that match
- Copy font from Site-Title, then paste in Site Description, under last line of text
- Make sure bracket } is on the line below font line
- Adjust site-title to 35px
- Keep or adjust site description font to 30px
- Set site-title width at 350-400px
- Set site description width to 400-550
- Both widths depend on length of title & length of description
